CHARLES STANDARD, OF DETROIT, MICHIGAN, ASSIGNOR OF TWO-FIFTHS TO ANDREWJ. BRADAU AND CLEMENT J. KARRER, OF DETROIT, INIIOHIGAN.

NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Application led August 22, 1908.

To all whom it 'may concern,.-

Be it known that I, CHARLES STANDARD, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements inNon-Refillable Bottles, of which the following is a specication,reference being had therein to the accompanying drawings.

This invention relates to that class of nonrellable bottles in which theneck of the bottle is provided with an automatic valve and the inventionconsists in the improved construction of said valve and also in thenovel construction and combination therewith of a cap all as more fullyhereinafter described and shown in the accompanying drawings, in which-Figure l is an aXial section through the neck of the bottle. Fig. 2 is alike section inverted. -Fig. 3 is a detached perspective of the valveand Fig. 4 is a detached perspective of the cap.

A represents the neck of the bottle.

B is an inverted cup shaped gravity valve provided with a central hollowstem a having apertures at or near its base.

The neck of the bottle is formed with a central passage C of suitablesize to freely admit and guide the stem of the valve and with theenlarged chamber D to accommodate the head thereof, a deep annulargroove l being formed at the bottom of the chamber to receive thedepending flange e of the valve.

E is a cap closing the neck of the bottle, it is secured thereinpermanently as by means of pins f, cement or in any other suitablemanner, there may also be a shoulder g formed on the bottle and a gasket7L may be interposed to make a tight joint. This cap is formed with acentral pour-out z' and over this is placed a transversely extendingguard j which forms the lateral eXits 7c to the pour out. The guard ispreferably formed in one piece with the cap and prevents the entranceVof any instrument for tampering with the valve.

On its underside the cap is provided with one or more projections Zadapted when the bottle is inverted to keep the valve out of contactwith the cap as shown in Fig. 2. When thus inverted the valve isunseated by gravity and the liquid in the bottle can pass out throughthe holes Z) into the groove d and thence around the flange e of thevalve to the pour out i and exits le.

The relative dimensions of the groove d and of the depending ange e ofthe valve are such that the flange e is not wholly withdrawn from thegroove in the open position of the valve, the walls of the two howeverare out of contact with each other and the liquid therefore can flowbetween as shown by the arrows. In this way a very tortuous passage isformed which provides additional security against tampering.

All the parts are preferably formed of glass or other vitreous materialand suitable provision is made for permanently securing the cap inposition upon the bottle.

What I claim as my invention is In a non-rellable bottle, thecombination with the neck of the bottle, of an inverted cup-shaped valveseated therein and provided with a downwardly projecting hollow valvestem guiding the valve in the neck of the bottle, an annular groovebeing formed therein to receive the depending flange of the valve andform annular spaces between the inner walls and the outer walls of thesame and the stem being provided with lateral openings adapted tomediately connect the space below the valve with the space above whenthe valve is unseated, and an apertured cap permanently secured upon theneck and adapted to limit the movement of the valve said movement beingless than the depth of the groove.

In testimony whereof I afix my signature in presence of two witnesses.

CHARLES STANDARD.
